Abstract

Building energy consumption is a substantial part of total energy consumption and is rising in the context of energy crises and environmental issues. To maximize energy savings and limit carbon emissions, the government recommends updating construction requirements. The Ministry of Housing and Urban-Rural Development of China proposed JGJ 26-2018 "Energy Saving Design Standard for Residential Structures in Extreme Cold and Cold Regions" in accordance to national policy. Several reports noted that some Chinese design requirements just stack energy-saving materials and technology without actually reducing energy consumption. This study proves the JGJ 26-2018's legitimacy. This essay first selects three major variables that have the largest impact on the energy consumption of buildings in extreme cold and cold areas—exterior walls, roofs, doors, and windows—and then gathers four cases of housing restoration of these three essential components according to JGJ 26-2018. The partial success of the strategy is proven by comparing energy consumption before and after building renovations, which provides a reference for energy-saving residential building design in severe cold and cold regions.
